An isosceles triangle is one which has two equal sides based on the origin of the word from Greek which means "equal legs". The angles that are opposite the equal sides are also equal. In an isosceles right triangle, one of the angles is a right angle, which means ...
Right angles also have some special properties that make them unique. For example, a right angle is the only type of angle where the sides opposite of each other are equal in length. This property is often used in construction and engineering when creating level surfaces or ensuring that objec...

The angles in a pair are located on opposite sides of segment C. The 2 angles in a pair of alternate exterior angles are congruent. Figure 8: Alternate exterior angles theorem proof. Lesson Summary Register to view this lesson Are you a student or a teacher? I am a student I am a ...
Among the triangle congruence axioms, the side-side-angle (SsA) axiom states that two triangles are congruent if and only if two pairs of corresponding sides and the angles opposite the longer sides are equal. We construct two triangle sequences in which the items satisfy a modified condition....
According to the angle bisector theorem, the angle bisector of a triangle divides the opposite side into two line segments that are proportional to the other two sides. Find how to prove the angle bisector theorem in an easy way at BYJU’S.
